Subject: [PATCH] misc: atsha204a: fix i2c address readout from DTS
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
This patch replaces use fdtdec_get_addr with simpler dev_read_addr().
fdtdec_get_addr doesn't work properly on ZynqMP-based (64bit) system. Although
not confirmed, it could be related to the fact, that quoting the documentation,
"This variant hard-codes the number of cells used to represent the address and
size based on sizeof(fdt_addr_t) and sizeof(fdt_size_t)".
